I believe yes if ur aro do take pellet..
Coz pellet can be stored, contain all the nutrients a fish needed, get something mid range is good enug, hikari mid range is good enug..if ur budget allows, go for tetraarowana pellet or hikari food stick..
So when u buy one can or tub of pellet..u can store em, u save petrol, u save time, no hassle to travel to lfs to buy live food, no need extra space or tank to keep live food, no live food gonna stuck inside filter or water pump or maybe a cricket escape the tank and there u go for the night trying to find where is that noisy *******..worse case, centipede escaped..not to forget live food got death rate..not all will survive..if u brought too much live food, u need to feed em to keep em alive especially when ur aro goes starving mode, live food will be left there..

But the cons for pellet or food stick is, need to train em to take..anyone with an aro trained to take pellet or food stick, dont ever switch to live food..surely will regret after some time..
